The quote form takes a ZIP code; for McLean that is 22043, 22101, 22102 (Census 2020 ZCTA to county subdivision and ZCTA to place relationship files, ZIP areas at least 20% inside the town, https://www2.census.gov/geo/docs/maps-data/data/rel2020/zcta520/tab20_zcta520_cousub20_natl.txt and https://www2.census.gov/geo/docs/maps-data/data/rel2020/zcta520/tab20_zcta520_place20_natl.txt, checked 2026-10-19).
Of the 17,147 occupied homes in McLean, 71% heat with natural gas, 1% with heating oil, 26% with electricity and 1% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US5148376, checked 2026-10-19).
Gas heats 71% of McLean against electricity at 26%, so most quotes here are a partial-home system that carries the shoulder seasons and the summer while the gas furnace handles the coldest nights, or a whole-home system when the house is ready for it.
McLean has about the Fairfax County oil share of 1% and 16 points less electric heat than the county's 42% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US51059, checked 2026-10-19).
McLean has 17,833 housing units, 2% built before 1940 and 56% before 1980, with 23% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US5148376, checked 2026-10-19).
McLean has 3 points more homes built after 2000 than the county's 20% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US51059, checked 2026-10-19).
The median McLean home was built in 1977 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US5148376, checked 2026-10-19) and the median home has 10 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US5148376, checked 2026-10-19).
81% of McLean homes are single-family detached, 0% are in two- to four-unit buildings and 9% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US5148376, checked 2026-10-19).
With 81% detached houses and 0% in small multi-family buildings, a McLean quote is usually one or two outdoor units with ducted or ductless heads sized room by room. With 14% of McLean homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US5148376, checked 2026-10-19), the landlord signs the quote in many of them.
McLean has 35 points more detached houses than Fairfax County overall (46%) and 20 points fewer five-plus-unit buildings than the county's 29% (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US51059, checked 2026-10-19).
Only 14% of McLean homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US5148376, checked 2026-10-19), so nearly every quote here is the resident talking to the installer directly, and the rebate goes to the person living in the house.
No electric utility is on file for McLean on this door yet, so this page does not name one; the name on the bill decides which rebate path applies.
Median household income in McLean is $250,001 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US5148376, checked 2026-10-19); many state and utility heat pump rebate programs set higher incentive tiers for income-qualifying households, so the household income on the application, not the town median, decides which level applies.
Heating design temperature: 14F. Source: ENERGY STAR Design Temperature Limit Reference Guide (2019 Edition), Fairfax County row, 99% heating, PDF pages 127 to 133 of 141 (Revised 11/11/2020), https://www.energystar.gov/sites/default/files/Design%20Temperature%20Limit%20Reference%20Guide%20(2019%20Ed)%20-%20ENERGY%20STAR%20Single-Family%20New%20Homes_Rev11.pdf, fetched 2026-10-19, 99%.
That 14F figure is the Fairfax County cold-day number a McLean heat pump is sized against, so ask the installer to show the system's heating output at 14F, not at the milder rating-label temperature.
Ask whether the quote is whole-home or partial-home, because with 71% of McLean on gas and 26% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median McLean home has 10 rooms and was built around 1977, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
